Abstract

Drill string component for top hammer drilling comprising a rod (13) surrounded by a tube packet (4,5). The rod is provided with a thickened section (14) for cooperation with a diameter reduction (15) in the tube packet which at upwards drilling is situated below the section (14). Through this flushing liquid is prevented from flowing out of the drill string when the drill string is extended. <IMAGE>

Description

467 419 2 Stàngen 13 är, lämpligen vid dess mitt, försedd med ett parti l4 med större diameter än övriga delar av stången. Ett lämpligt sätt att ástdkomma detta förtjockade parti är att friktionssvetsa två stänger för bildande av stången 13. Rördelen 4 är försedd med en diameterreduceríng 15 som vid uppåtriktad borrning är belägen nedanför partit 14 på stången 13. Rördelen 5 är försedd med en diameterreduceríng 16 försedd med ett antal spår 17 för passage av spolvätska. Mellan diameterreduceringarna 15,16 har rörpaketet en invändig diameter som är större än diametern på partit 14 så att spolvätska kan passera förbi partit 14. Vid uppàtriktad borrning pressar stången i borrsträngskomponenten nedanför upp stången 13 till ett läge såsom visat i fig 2 varigenom spolvätska kan passera genom borrsträngen till borrkronan 3. The rod 13 is, suitably at its center, provided with a portion 14 of larger diameter than other parts of the rod. A suitable way of accessing this thickened portion is to friction weld two rods to form the rod 13. The pipe part 4 is provided with a diameter reduction 15 which, when drilled upwards, is located below the portion 14 of the rod 13. The pipe part 5 is provided with a diameter reduction 16 provided with a number of grooves 17 for the passage of flushing liquid. Between the diameter reducers 15,16, the pipe package has an inner diameter which is larger than the diameter of the portion 14 so that flushing liquid can pass past the portion 14. During upward drilling, the rod in the drill string component below presses up the rod 13 to a position as shown in Fig. through the drill string to the drill bit 3.

Vid skarvning av borrsträngen backas bergborrmaskinen så att stången 13 sjunker från det i fig 2 visade läget till ett läge där partit 14 kommer till anliggning mot díameterreduceringen 15 så att tätning åstadkommes mellan stången 13 och rörpaketet. Härigenom förhindras att spolvätska ovanför tätníngen rinner ut ur borrsträngen. »_When splicing the drill string, the rock drilling machine is reversed so that the rod 13 sinks from the position shown in Fig. 2 to a position where the portion 14 comes into abutment against the diameter reduction 15 so that a seal is provided between the rod 13 and the pipe package. This prevents flushing fluid above the seal from flowing out of the drill string. »_

1. 3 467 419 Patentkrav: l. Borrsträngskomponent för sammankoppling med andra likadana borrsträngskomponenter till en borrsträng för topphammarborrning innefattande en stång (13) för överföring av slagenergi mellan en bergborrmaskin (l) och en vid borrsträngens främre ände anordnad borrkrona (3) samt ett stången omgivande rörpaket (4,5) innefattande två rördelar för överförande av rotation mellan bergborrmaskinen och borrkronan, k ä n n e t e c k n a d a v att sagda stång (13) är försedd med ett parti (14) med större diameter än övriga delar av stången samt att sagda rörpaket (4,5) innefattar en diameterreducering (15) som vid uppàtriktad borrning är belägen nedanför sagda parti med större diameter, varvid sagda parti med större diameter och sagda diameterreducering är så utformade att de kan tätande samverka med varandra. bas900073,467,419 Claims: 1. A drill string component for interconnection with other similar drill string components to a drill string for top hammer drilling comprising a rod (13) for transferring impact energy between a rock drilling machine (1) and a drill bit (3) arranged at the front end of the drill string (3). the rod surrounding pipe package (4,5) comprising two pipe parts for transmitting rotation between the rock drill and the drill bit, characterized in that said rod (13) is provided with a portion (14) with a larger diameter than other parts of the rod and that said pipe package ( 4.5) comprises a diameter reduction (15) which, when drilled upwards, is located below said larger diameter portion, said larger diameter portion and said diameter reduction being designed so that they can co-operate sealingly with each other. bas90007
